Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607672, here are decompositions:

43 + 31607629 = 31607672
73 + 31607599 = 31607672
199 + 31607473 = 31607672
211 + 31607461 = 31607672
223 + 31607449 = 31607672
331 + 31607341 = 31607672
373 + 31607299 = 31607672
379 + 31607293 = 31607672

Showing the first eight; more decompositions exist.
